You don't need to leave Claude. You just need to stop paying full retail. ClaudeAPI.cheap is a drop-in proxy: same Anthropic SDK, same models, same context window, same streaming, same tool calls. 70-80% off official prices.
Pro plan is $19 lifetime — paid once, never again. Free Basic plan also exists at 70% off.
We're a paying customer of Anthropic's API, buying credit in bulk. We resell our credit to you at our markup — and crypto-only payment removes Stripe fees + chargeback risk, which is what makes a deeper discount work financially.
Your requests hit the same Anthropic infrastructure. We forward them as-is, strip vendor-fingerprint headers, return the response. No model modifications, no caching, no quality loss. Just thin proxy with bulk-discount math.
No code rewrite. The Python and Node SDKs work unchanged with our base URL.
Full SSE streaming. Tool/function calls forwarded. Tool result mapping unchanged.
90% read discount on cache hits, applied to our 80%-off price. Lower than Anthropic direct.
All image inputs work the same way. Forwarded transparently.
200k for Opus 4.7 / Sonnet 4.6 / Haiku 4.5. Same max output.
Identical model. We're a routing layer, not a fine-tune. Output is byte-for-byte the same except stripped headers.
# Before — Anthropic direct
client = Anthropic(api_key="sk-ant-...")
# After — ClaudeAPI.cheap (the only change)
client = Anthropic(
base_url="https://claudeapi.cheap/api/proxy",
api_key="sk-cc-your-key-here",
)Or set ANTHROPIC_BASE_URL + ANTHROPIC_AUTH_TOKEN env vars and zero code changes anywhere — every Anthropic-SDK-based tool inherits. See the env-var trick.
Same sk-cc-... key works for OpenAI's GPT-5 family and Google's Gemini 3 Pro / Flash too — via our /v1/chat/completions endpoint. One key, three vendors. Useful for agents that A/B across providers.
